Fig. 1! a detail side view of another form of lockin device for the regulating plate. i have shown my invention in the present nstance applied to a front-strike ty ewritmg machine. It should be understoo however, that the line spacing mechanism fornb ing the subj cot-matter of the present inventlon may be applied to various forms of mes. 1e top plate 1 of the machine is so ported on corner osts 2 and has upwardly extending lugs 3 t at sup ort fixed carriage rails 4 having substantia y V-shapcd bearing faces that coiiperate with crossed antifnction rollers The rollers 5 likewise cooperate with substantially V shaped tracks 6 on a carriage 7 in order to suppoit it in its travel from side to side of the machine. A vertically movable shift rail 8 receives its vertical movement. through a rod or rods 9 that are actuated by any suitable shift key. The shift rail 8 so )ports a grooved roller 10 which is connected to a platen frame by a screw pivot 12. The laten frame is con nected to the carriage y parallel links 13, 14, each of the links 13 bei q pivotally connected to a side plate 11 of ihe platen frame at 15 and to the carriage at 16. Each link H is in a like manner pivoted at 17 to a side plate of the platen frame and is pivoted at 13 to :1 depending arm 19 on the carriage. The side plates 11 have hearing openings therein for the reception of a platen shaft 21 on which a platen 2-2 is mounted.

A line spacing ratchet wheel 23 is secured at the right hand end of the platen and a detcnt roller 24 of the usual construction bears against the teeth '25 of the line spacing wheel to maintain the wheel against accidental displacement in the position to which it is moved by the line spacing mechanism. This detent roller li mounted upon the forward end of a flat spring 26, the rear end of the spring being secured to the platen frame by a screw 27. The ri ht hand side of the can riage is provided with a bearing 28 that ma. be formed integral with the carriage and has a central bore for the reception of a rock shaft 29 which extends at its rear end beyond the hearing and has secured to it a crank arm 30. '1 his crank arm is in the nature of a cylindrical pin which projects from a collar 31 that is apertured at 32 for the reception of a pin 33 which passes through the openings 32 and through a transverse opening in the shaft 29 to rigidly connect the crank arm 30 to the rock shaft.

The bore in the bearing 98 is enlargul at 34 (Fig. 9) for the reception of a coiled restoring spring 35 which surrounds the rock shaft 29 and one end 36 of which is seated in an opening 37 in the hearing. The other end 35 of the spring is seated in an opening 39 in a bearin sleeve or collar 40. The central bore in tins collar receives the rock shaft and a reduced portion 41 of the sleeve is received and seated within the bore 34 in the hearing '28, so as to turn therein. A shoulder 40 formed atthe junction of the enlarged and reduced portions of the sleeve is adapted to bear against one end of the hearing 28. A. set screw -12 extends through a threaded opening in the sleeve 40 and bears at its inner end against the rock shaft 29 so as to rigidly connect the sleeve to the rock shaft. A circumferential shoulder 43 is formed on the rock shaft and bears against the sleeve 40. It will be seen that from this construction the parts can be readily assembled or disconnected when the collar 31 and sleeve 40 prevent the longitudinal movement of the rock shaft 29 in its bearing; that the restoring spring 35 is housed within the bearing 28; that the construction presents a neat appearance; and strong and etiicient means for transmitting movementto the line spacing pawl are pro vided as will hereinafter more clearly appear.

The forward end of the rock shaft 29 has a downwardly extending crank arm 4.4 with a tin 1' piece -15 at the free end thereof. The isposition of this crank arm is such that the pressure exerted from left to right thereon tends to turn the rock shaft 29 and thereby actuate the line spacing mechanism and at the same time to return the carriage top plate to be a to the right across the The cylindrica pin new line of writing.

or crank arm 30 hereinbefore referred to carries one member 46 of a universal or ball and socket joint. The member 46 constitutes a spherical head which is perforated in order that it may be mounted to turn and to slide longitudinally on the in or crank arm 30 and constitute in e ect an anti-friction roller as well as one member of a universal joint (Fig. 13). This ball is adapted to be received in an elon ted opening or slot 47 in an angle lever 8%, said slot having undercut walls 48 that are curved to correspond to the curvature of the ball desired and that A I which is received therein, as clearly indicated in Fig. 11. The ball 46 may be introduced into its bearing slot 47 through an enlarged o ening 49 at one end of i the slot -17 an when centrally ositioned l in the enlarged opening, may e moved l longitudinally along the slot 47 so as to be seated within the combined socket and slide way formed by the rooved walls 48 of the 1 slot. It will be on erstood that in the opj eration of the machine the ball 46 never passes to a point where it will register with p the enlarged opening 49 and there is no liability therefore of the parts being accidentally disconnected. The angular lever 50 is pivoted at 51 to the right hand end of the carriage-gland the upwardly and forwardly exten arm thereof is pivoted at 52 to a rearward y extending link 53 which, in turn, is pivoted at 54 to a line spacin pawl 55. This line spacing pawl is ivoted intermediate of its ends at 56 to a vi ratin line spacing pawl carrier 57 that is adapted to turn on an axis coincident with the axis of the platen. From an examination of Fig. 12 it will be observed that the righthand end plate 11 of the platen frame has a threaded opening therein which receives a threaded end 58 of a bearing sleeve. This bearing sleeve has an angular or hexagonal portion 59 by means of which the end 58 can be threaded into its opening in the platen frame and the hexagonal portion con- 5 stitutes a shoulder that is adapted to bear against the outer side of the platen frame. An outwardly extend' portion 60 is formed on the sleeve an the central bore extends through the parts 58, 59 and 60 which constitute the sleeve for the reception of the platen shaft.- The extension 60 passes into an openin 61 formed in the right hand side bar 0 the carriage and is adapted to co-act. with screw stops 62, 63 (Fig. 1) carried by the carriage and limit the upward and downward shifting movement of the platen as it is shifted from upper to lower case and vice versa.

A hearing collar 64 is received on the threaded end 58 of the bearing sleeve as shown in Fig. 12 and bears at its inner end against t ie right hand side plate 11 of the p aten frame and forms a peripheral hearing at 65 for the bearing portion 66 of the line spacing pawl carrier 57. A flange or hexagonal head 67 is formed at one end of the bearing collar 64 so as to cotiperate with the bearing portion 66 of the pawl carrier and prevent it from being displaced from its hearing. The head 67 also enables the collar 64 to be readily secured in place on the sleeve 58-59-60 and to lock said sleeve against accidental displacement.

A plate or adjusting device 68 is provided for regulating the extent of hne 1 spacing movement of the line spacing pawl and its carrier. This plate is mounted on the peripheral bearing 65 of the sleeve 64 and is situated between the carrier 57 and the right hand and plate 11 of the platen frame. The bearing opening 69 of the regulating plate is enlarged in the direction of the length of the plate as indicated in Figs. 5. 6, 7 and 8 in order to afford a movement of the plate at right. angles to or radially of the axis of the platen as well as a turning movement around the peripheral bearing surface 65. The lower end of the plate carries a pin 70 by which one end of a contractile spring 71 may be connected thereto, the other end of the spring being secured to a pin 72 that rojects inwardly from the right hand end plate 11 of the platen frame. The upper end of the regulating plate 68 is provided with a finger piece 73 by means of which it may receive a movement against the tension of the spring 71 at right angles to the axis of theplaten and may likewise he turned around its hearing 65. The right hand end plate 11 of the platen frame is formed with an upwardly extending portion H and three locking or engaging openings T5. T6 and 77 are formed in the edge thereof. A laterally projecting locking pin T8 extends from the regulating plate 68 and is adapted to be seated in an one of the engaging openings 75, T6 or 77. Thus, in order to adjust the plate 68 it is merely neccssary to move the plate upwardly against the tension of its spring 71 and to give it a partial rotation in order to bring the locking pin 78 opposite the opening '75, T6 or T? where it is desired to secure the plate, a stop pin 7: being employed to prevent the plate from being moved too far forward. The locking pin may then be seated in the desired opening and the plate (38 will be maintained in this position against. accidental displacement by the spring '71. Thus. the regulating plate 68 is provided with a laterally projecting stop pin T9 with which the pawl carrier 57 cooperates when the latter is in its normal position as indicated in Fig. 4. From this it will be niderstoml that the position of the regulating plate 68 determines the initial position of the stop pin 79 and the stop pin 79 determines the initial position of the carrier 57 and consequently the line spacing pawl. and in this manner determines the extent of line spacing move ment. If. for instance, an adjustment of the locking pin 73 in the engaging opening 77 is eliected, then the line spacing pawl will have the shortestextent of throw and the line spacing wheel will be turned one tooth, whereas if the locking pin 78 is adjusted in the engaging opening 4'6 then the line spacing pawl will have a greater extent of movement. and the platen will be rotated an extent corresponding tothe distance betwcen two teeth of the line spacing wheel,

whereas if the locking pin is adjusted in the engaging opening 75, t to line spacing pawl will receive its greatest extent of throw and will rotate the platen to the extent corresponding to the distance between three teeth of the ratchet wheel.

in Fig. 14 I have shown a different form of lockin plate for retaining the adjustable plate 68 in position. Thus, instead of forming the locking or engaging openings 75. 7(3 and 77 directly in the right hand end plate ll of the platen frame. as in the construction )reviously described. I employ a detachalilc plate l'l which is secured to the right-hand end plate 11 by screws 11". T his plate has locking openings T5. T6 and 77 cut. in the upper edge thereof for the reception of the locking pin TS as in the construction previously described and a stop 11. corresponding to the stop pin 78 in the previously described construction. is formed as a part of the plate 11 to limit, the forward swinging movement of the plate (SH. The object of making the locking plate 11- detachable is to enable the same line spacing mechanism to be used in connection with any of the ditferent characters of line spacing wheels now in use: some having twenty nine teeth. some thirty-thwe and so on. the teeth being differently spaced and of diti'ercnt sizes in different wheels. \Vhen a line spacing wheel of one character is suhsti lntcd for another in my machine it i l'nerely necessar to detach one plate 11 and substitute another having the openings therein for it and no other change in the mechanism is necessary.

From the foregoing it will be seen that the line spacing .pawl at the last portion of its movement is always brought to a given point. although the initial position of the pawl is varied in order to change the extent of line spacing movement to be given to the platen. heretof re pointed out the line spacing pawl is pivoted intermediate of its ends. one end of the pawl being formed with an cngaigingi nose 0 whi h coiagerates with the teeth of the line spacing wheel. whereas the tail S1 of the pawl is formed with a camlike surface 82 which is adapted to coliperate with the detent roller 24 at the last portion oi the line spacing movement and to force said detcnt toward the axis of the platen and thus into more firmer engagement with the line spacing 1100]. The pressure thus exerted at the same time forces: the engaging nose S0 of the line spacing pawl into firmcr cngagement with the tecth of the line sparlug wheel, thereby preventing any liahilii) of overthrow of tho platen by a violent actuation of the line spacing nn'rlmnisln. A stop pin 83 projects inwardly from the right hand end plate ll of the platen frame and projects into the path of the carrier fol the line spacing pawl as indicated in Fig. 1''.

' These parts are brou 'ht. into cooperation on the pawl has exerted pressure on the detent roller and their coo-pomitiolrpi'cv'ciits the entire ,force of the-line" af.'cr the ram 82 spacing movement of thepnwl and carrier from being taken up by tie dctent roller.

-L slop pin 6% is riveted to the pawl as shown in Fig. 12 and projects laterally therefrom through a hole in the carrier, which .hole

is sli htly lar 'er than the diameter. of the pin, l llllS atl'ordinig a limited extent of movementof the paw pentlently of its carrier in order to enable the pawl to he moved mto and outof engr renient with the teeth of the line spacing wheel and then to ellect a bodily movement of the pawl antlcarrier through the pressure up died to the pawl.

n the operation of the device the regulat-.

ing plate 68 may be adjusted so that the hackingpin 78 thereon is seated in one ofthe engaging o )enings 75. 76 or 77 in order to determine tie extent of line spacing movement. The adjustment of the re lilati plate in the manner hereinhefore v will determine the normal position'o'f the finger piece 45 as indicated at a, b or-cin Fig. 3. An actuation of the finger piece 45 thereafter will carry it to the position indicated at (I, thereby turning the crank arm movement of the link 53 will effect, a movement of the awl, its carrier and the line spacing whee about the axis 21 until the pawl cooperates with the detent roller 24 and the carrier 5? is brought into cooperation with the fixed stop 83 when further movement of the )arts h prevented. When pressure on the hnger piece 45 is released the restoring spring 35 will turn the crank arm 30 back to the initial position, thereby turning the angular lever 50 to its initial position,

withdrawing the owl from engagement with the-line spacing wheel and restoring the pawl and its carrier to the normal position.

It will he observed that the construction is such that the line spacing mechanism is carried in part by the platen frame and in part. by the carriage,- and that, nevertheless,

the platen frame may be shifted independently of the carriage to either cnso position 7 without atlectiug'jthe action of the line spacing mechanism. Durin the shifting-move ment of the platen to c tlou thereof, the line spacing ratchet vw about the pivot 56"indethat the an and that duri' di cribec for actuating $21 p on the rockshaft, a leveractuatedo'by-said.

It will also be seen that. notwithstanding "this relative movement; be-

'It will be un- (lGlStQQd, therefore, that during the actuation of the-line spacing mechanism, a downward inovementk of'the crank arm 30 will transm tmov enientto the angular lever -50 this movement of the pairts the M1146 w receive a sliding movement on the crank arm or pini30, longitudinally thereof, and will at the same-time receive a turning movement nroundthe pin 30 and will also receive ashding movementflongitudinally ofthe slot 47 and will turn 1n the bearing walls 48- of the slot. In one aspect of the invention the connection between the rock shaft 29 and the lever or actuating de vice 50-, constitutesa pin and slot connection. From another aspect of the invention said cmmection constitutes a universal joint or ball and Socket connection, and from still another aspect 01 the invention the connection constitutes a combined universal oint 1 and sliding or pin and slot connectlon between the parts mquestion.

Various changes may be'made without departing from myinvention.
